鄂北豫西南的漫岗平原和平缓丘陵上,广泛分布着上更新统黄土(Q_3)上发育的土壤。在中国土壤图(1976年),中国土壤和土壤分区图(1981年),划为粘盘黄棕壤或黄褐土。以往有关这类土壤的研究报道,多以苏、皖的粘盘黄棕壤为对象。近年来,笔者结合鄂北土壤普查,对鄂北豫西南的黄褐土进行了一些考察研究。本文就黄褐土的某些发生学特征,及其与鄂中下蜀黄土上发育的土壤(称为典型黄棕壤,简称黄棕壤)的差别,并对它在土壤分类中的地位,提出一些看法,以供讨论。
On the Manang plain and gentle hills in the southwestern part of Henan Province, the soils developed on the Upper Pleistocene loess (Q_3) are widely distributed. In China Soil Map (1976), China Soil and Soil Zoning Map (1981), it is classified as yellowish brown clay or yellowish brown clay. Previous studies on this type of soil have reported that more yellowish-brown soil in the dish of Su and Anhui is the target. In recent years, the author combined with the census of northern Hubei soil, to investigate some yellow cinnamon soil in southwestern Henan Province. In this paper, some characteristics of the occurrence of yellow cinnamon soil, and the Yellow River in Hubei and the development of the soil on the soil (called yellow brown soil, referred to as yellow brown soil) difference, and its position in soil classification, Make some comments for discussion.
